连续四张NOAA-9红外图像显示，拉布拉多海岸外的海冰表面每天都在变暖。对于尺度约为100公里的三个子域，假设地表升温是在假设一个像素的升温与冰压实度成正比的情况下获得的，而冰压实度是由可见(白天)图像的亮度给出的。求解了一维冰雪热传导方程。提出了一种算法来估计雪层厚度，这是计算通过冰的热通量所必需的。>；
Four consecutive NOAA-9 infrared images show diurnal warming of the sea-ice surface off the coast of Labrador. For three subdomains with scales of approximately 100 km, the warming of the surface is obtained on the assumption that the warming of the surface is obtained on the assumption that the warming in one pixel is proportional to ice compactness, which is given in turn by brightness of a visible (daytime) image. A one-dimensional heat transfer equation for snow and ice is solved. An algorithm to estimate the snow thickness, which is required to calculate the heat flux through ice, from this extra warming is proposed. >
